One of my Dad's friends has a 700 it's a nice little car, and I think it worth a pretty penny now. I would have used a R series flat twin so I could put it back to original, but it could have been a roller, rusted out, or both. Oh I work on Sundays, and when I was driving to my first call this morning I saw 3 cars on the AZ 101 today. 1 Lamborghini Miura, 1 Ferrari 250 GT vert, and an Alfa out for a Sunday morning drive ... I was a little wowed!
